The random atom color toolbar button is just for laughs — I’ll retire that one when I add C-alpha trace. The C-alpha trace plus side-chain doesn’t seem too different from full backbone + side chain in visual complexity, and backbone + sidechain already has a toolbar button (show all atoms). I’m thinking maybe that would be a toolbar button you could add as a customization. I plan to add a command soon where you can add new toolbar buttons (you specify and image file for icon and the command to execute using a command e.g. "toolbar add “CA trace” icon iconfile.png command "show selAtoms & @CA” shortcut ca” and it would be remembered in a preference file. Another useful one would be your thick backbone and thin side-chain sticks.<br class=""><br class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>Tom<br class=""><br class=""><br class=""><blockquote type="cite" class="">On May 26, 2017, at 7:35 AM, Oliver Clarke wrote:<br class=""><br class="">Hi,<br class=""><br class="">Frequently when looking at models in medium resolution maps (~4-5 Å), it is valuable to view the C-alpha trace when assessing model map fit (or making figures to show such).<span class="Apple-converted-space"> </span><br class=""><br class="">At slightly higher resolution, where side chains are obvious but backbone torsions cannot be modeled based on the map alone, representing the C-alpha trace with sidechains displayed is often desirable (examples of both attached).<br class=""><br class="">It looks like there is space in the upper toolbar for additional buttons - perhaps adding a button for a Calpha trace representation (equivalent would be P for nuclei acids) and one for a Calpha+sidechain/base representation may be worth considering?
